I also faced same!!

guys.. any details on how to solve my problem?... also I forgot to mention I was using VOIP service... I canceled the VOIP and I started getting these problems...

plz.. can anyone shed some light on this issue..??

@karthikvj.
Please mention your set up with the VOIP unit.
Have you removed the VOIP unit ? ( what is the model/make ?).

You can try a RESET of the modem AX MT882 and try again.
(even though you had mentioned earlier it worked ok in your office )

@abins
presume you had gone through the whole thread and
problem still exists. confirm.

I have removed the VOIP now.. I don't remember the VOIP model name.. I will let u know.... I have tried reseting the model and all... still no ping response from the modem...

also.. I tried disconnecting the ADSL line from modem.. I connected only the modem to my PC ethernet.. I still was not able to ping to the modem default gateway...

(a)Now are you connected to Internet with a different modem with the same computer/desktop ?

no I was using another system that has internet access...

I am at home now... I logged into WinXP is safe Mode with Network enabled.. I am able to ping to default gateway and Internet is working too... What can be the normal.. its not working in normal mode..?? malware or virus..??

Try system restore. Restore to a previous point in which you had no problems.

guys...
yesterday the internet was working fine in windows safe mode and also in ubuntu live CD... after like 2 hours the problem started again... plz help..!!!!!!!!!!!
